DOOR-KNOB FASTENING.

SPECIFICATION forming part of Letters Patent No. 470,072, datedMarch 1,1892.

Application filed September 30, 1891- Serial No. 407,348- (No model.)

To all whom it may concern.-

Be it known thatI, JOHN H. ORMsBY, a citi-- zen of the United States,and a resident of Bolton Landing, in the county of Warren and State ofNew York, have invented certain new and useful Improvements in Door-KnobFastenings; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical 10ngitudinal section. Fig. 2 is aView of the knob-plate, the parts being detached.

This invention has relation to means for fastening door-knobs tospindles; and it consists in the novel construction and combina-.

tion of parts, as hereinafter described.

In the accompanying drawings, the letter A designates a knob having theinner end of its shank portion 13 provided with a shoulder or flange a.Said shank also has an angular aperture 1), which receives the end ofthe spindle or bar O.

D is the knob-plate fitting around said spindle and having therein agroove d to receive the shoulder or flange a of the knobshank. Thisplate is formed in two pieces D and D to permit it to he slipped overand into engagement with the shoulder a after the knob is applied to thedoor. The section D is preferably wedge-shape, fitting closely intosection D. Said sections are held in place by screws f.

It will be seen that by. this construction I obviate the use of thescrew ordinarily. used ordinary manner and having a central perfo-'ration to receive the knob-shank, the inner face of said plate having agroove 01 around said perforation to receive the said shoulder or flangeand formed in two sections, the smaller wedge-shaped section beingremovable, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN II. ORIVISBY. Vitnesses:
